With nothing new to add, it does it's best.

Rating: 6/10 (25 July 2013)

From the intro titles of Pacific Rim that sweep in about ten minutes into the movie, the dance-style soundtrack shows just what kind of movie Pacific Rim is going to be.
Or rather, what it ought to be.
The film's action is spectacular, as it's battles between giant robots and Godzilla-like creatures are chaotic but clear and precise. It's nice to see a movie with clear fight scenes these days. The movie delivers entirely on the action front.
On about everything else, it stumbles.
The movie consistently fights with itself whether it is a serious action drama or a comic-booky cheese-fest. There are moments where it is obvious that Del Toro is winking at you but the very next scene contains attempts dramatic dialogue from a dreadfully written one of two main characters. One of the most regrettable pieces of dialog occurs when the main character says "But Gypsy Danger is analog!".
Although I must admit that I am very partial to Charlie Day and the It's Always Sunny camp, the attempted comic relief relied entirely on the body movements of Charlie Day and Burn Gorman because of the weak script.
Pacific Rim would have been much more successful and enjoyable if it solely stuck to being a cheesy comic-book film rather than become a predictable and weak attempt at drama.
